christmas clothes for walmart and other brands. brian ross investigates. dream big. a powerball jackpot of almost $500 million. we search for secrets that could increase the chance of a win. and american hero. the young woman whose fierce determination found osama bin laden. the true story behind the movie, of the woman right there with s.e.a.l. team 6. >> and you're going to count on me. good evening, and welcome back from the holidays, and tonight all of us together are on the verge of making history simply by clicking "buy" on the computer screen. it's the new american tradition, cyber monday, shopping online and what happens in the next few hours could have a big effect on the health of the nation's

economy, and you can see how much right here. online shopping on this one day has nearly tripled in the last seven years. abc's neal karlinsky tells us what we're buying and why the big stores sometimes know even before we do. >> reporter: across the country today from so-called "couch commerce" at home to the cubicle at work, americans were buying at a record pace and having every bit of their online behavior tracked. we know that at least half of cyber monday purchases were made from a work computer while the boss wasn't looking, mainly between noon and 2:00 p.m. browsing reaches a peak in the evening. we know that today the most purchased items are consumer electronics including phones and tablets followed by clothing like jeans and sweaters, and in a growing trend, we know that more than ever before people are doing it on the go from a mobile device, many while walking the aisles inside a store. in fact, an estimated 48 million

shoppers now do something called "showrooming," checking out a product or price in the real world before buying it online. >> it's personalized shopping, and it's really becoming quite sophisticated. and in a sense it's benefiting the consumer. >> reporter: no one has perfected online shopping like amazon, which gave us rare access to one of the company's 80 massive fulfillment centers where we ordered a video game, watched it pulled from a shelf by hand then sent on its way through miles of conveyer belts before being boxed up. all in just a matter of hours. >> cyber monday is a big deal for us. it's real. it's not something made up for us to get some hype. >> reporter: the company doesn't only sell just about everything, it uses sophisticated programs to track your online habits, a fully customized shopping experience to not only match prices, but increasingly match your desires. i log on and automatically you guys are suggesting i might want this and that.

>> we have teams of super smart people who build algorithms to create personalized recommendations for our customers. >> reporter: one thing about online shopping, people return a lot more. up to 35% of online purchases are returned versus only about 18% from traditional stores. as for that video game that i purchased from amazon, it showed up from phoenix almost quicker than i did with a handwritten message i put inside "happy holidays from abc news." diane? >> well done, neal. if you're also expecting a delivery, we have a heads-up for you. two videos that offer a real warning tonight. watch this one from fremont, california. a homeowner caught a delivery man dropping off a box, and then minutes later, this woman strolls right up and steals it, making off with a new pair of black boots, even grabbing a bag of canned food that had been set out for a charity. and here's another home owner video. in ft. worth, texas, the u.p.s.

man places a package near a bush, but a woman is watching and makes off with a $1,500 computer inside. so delivery companies are urging every shopper to ask for signed proof of delivery or send packages to an address where you know someone is going to be there. and now the looming threat to every american family budget, look at this. the countdown on, 36 days until the nation goes over that fiscal cliff. a tax hike for everyone on new year's day unless lawmakers end their long gridlock, and today we did see a sign the paralysis may be ending. a republican mutiny against a man who had convinced them to take a pledge. abc's jonathan karl on the big picture from washington tonight. >> reporter: it's been an article of republican faith for decades, no tax increases of any kind, period. behind it all, this man, grover norquist, considered one of the most powerful men in washington. since he worked for ronald

reagan in the 1980s, he's gotten virtually every elected republican to sign a pledge promising no tax increases. >> a taxpayer-friendly congress. >> reporter: they sign it to help get elected and don't violate it for fear of getting hammered for breaking their word. now how many of these things have been signed? >> pledges? >> reporter: yes. >> thousands over the years. >> reporter: he keeps them all on file. here's john boehner's pledge signed 20 years ago. if somebody signed this 10 years ago or 18 years ago, 20 years ago, are they still bound by it? >> now when you got married, did your wife understand there was an expiration date on that promise? when you borrowed money to buy your house, did you say, "oh geez, that mortgage? that was ten years ago. you're still asking me for money?" you know, if you make a commitment, you make a commitment. >> reporter: the pledge is the biggest obstacle to any deal that would raise taxes, but with a budget crisis on the horizon and a re-elected president insisting on tax increases, some republicans are now thinking the unthinkable, ditching the

pledge. >> i will violate the pledge, long story short, for the good of the country. >> i'm not obligated on the pledge. >> the world has changed, and the economic situation is different. >> reporter: and while virtually every republican in the past signed it, nearly a third of the newly elected house republicans refused to sign it this time. republicans ditching the pledge could be a big step towards a deal with the president. and tonight, diane, another republican senator, lisa murkowski, tells abc news that she, too, would be willing to break the pledge in exchange for spending cuts. >> all right. if this is a new sign of flexibility, jon, when are you looking to see for sure if there's going to be a deal? >> reporter: well, they're negotiating quietly behind closed doors. still no sign of a deal. time is running out and, remember, diane, they remain far apart on the big question. republicans, some may be willing to raise taxes by cutting loopholes, but they still don't want to raise rates, and that's what the president wants. >> okay, jon, thanks to you. tonight, walmart and other american companies are looking at a tragedy overseas among

workers making clothes for their stores to sell at christmas. thousands of people in bangladesh poured into the streets today mourning more than a hundred garment workers killed in an inferno over the weekend, a factory with no fire exit. abc's chief investigative correspondent brian ross has more. >> reporter: the tazreen factory was a death trap, and it was no secret. the fire broke out on the ground floor as hundreds of workers were upstairs on a late-night shift producing fleece jackets and trousers for the holiday rush at american stores including walmart according to labor rights groups. fire officials say the only way out was down open staircases that fed right into the flames. some workers died as they jumped from higher floors. firemen have now recovered at least 112 bodies in what has become a grisly fact of life for workers in bangladesh garment factories.

as we found in an abc news investigation earlier this year, many of the best-known american retailers including tommy hilfiger and the gap have been drawn to bangladesh, drawn by the cheapest labor in the world, as low as 21 cents an hour, producing clothes in often crowded, deplorable conditions that would be illegal most anywhere else, certainly in the u.s. >> the cheapest place, the worst conditions, the most dangerous conditions for workers, and yet orders continue to pour in. >> reporter: it turns out walmart inspectors warned last year that the factory had violations and/or conditions which were deemed to be high risk according to a document on the factory website, yet walmart clothes continued to be made at the factory, according to workers' groups who found clothing with walmart's private label, faded glory, in the burned out remains late this weekend. walmart confirmed one of the suppliers did use that factory to make their clothes, but walmart, famed for its tight

control of the suplly chain, says the order was placed with the factory without its knowledge and violated walmart policy. walmart says it fired that supplier, and its thoughts are with the families of those who died making that clothing. >> thank you. and back home we have learned about a new development in that salmonella outbreak linked to peanut butter two months ago. the fda shut down operations at the largest organic peanut butter processor in the country, and it's owned by sunland. you'll remember it. the agency found salmonella all over the plant in new mexico. last september the outbreak spread to 20 states, and it sickened 41 people. and there was also a big warning about health and your medication today. new proof that a staple in american kitchens, grapefruit, can trigger an overdose of popular drugs, a startling headline for millions of americans, and abc's chief medical editor, dr. richard besser, here with some answers. rich, grapefruit, grapefruit?

>> that's right. it's all about pills, grapefruit and a problem you don't need to have. grapefruit can have terrible interactions with certain medications, and the list of drugs that is involved has been growing. just five years ago there were only 17 drugs we worried about. now that's gone up to 85, and take a look at what drugs those are, statins and heart drugs, sleeping pills, antibiotics, seizure medications, anti-cancer drugs, a long list. >> and is it just eating the grapefruit, or is it the juice alone? which is it? >> it's all grapefruit. grapefruit is the forbidden fruit. >> whether they eat it or drink it as a juice? >> it's that bitterness that causes the problem. take a look at this. just drinking one glass of grapefruit or eating one grapefruit is enough to have the effect, and it can last for up to 24 hours. so even if you have the grapefruit hours before or after your pill, you're still going to have the problem. the chemical in grapefruit makes

the drug more potent by preventing your body from breaking it down and gives you an overdose of the drug, and it can do serious damage. it can stop your heart. it can damage your kidneys, serious problems. >> so a list of the medications -- >> we have that on abcnews.com. look at the list, look at your drugs. if any of them are on there, talk to your doctor and stop eating grapefruit. >> dr. richard besser, a big warning out tonight. and another about those inflatable bounce houses, a fixture of children's parties for so many american families. a report today says a child is hurt every 46 minutes in one of them, every 46 minutes, and abc's bazi kanani has the new epidemic of injuries. >> oh, my god. >> reporter: a startling example of what can go very wrong. in this instance in new york, a wind gust hurled a bounce house across a field with children still inside. 13 people were hurt. a new study shows a 15-fold increase in bouncer-related injuries over the last two decades now sending an average of 31 children to the emergency

room each day with broken bones, sprains, concussions. you always want these staked down. >> you want to make sure they're staked down carefully, and never use it on a windy day. >> reporter: he requires parents to sign a safety contract, no overloading, no mixing bigger kids with smaller kids, and constant supervision. this is meant for bouncing, not for flipping. >> right, no flipping, wrestling or roughhousing. >> reporter: advice to keep kids from flying, colliding or falling victim to an increasingly childhood hazard. bazi kanani, abc news, new york. and still ahead on "world news," it's powerball time with a record-breaking jackpot. we searched for secrets that could increase the chance of a win.
